I see no reason to believe that ROR will be that much better than Eller.

ROR's number 1 linemate last season wwas Gabriel Landeskog. He also got over 15 minutes a game of ice time last year. In comparis.n, Eller's number 1 linemate was Travis Moen, and his ice time was about 12:30, or about 17% less than ROR. He's also 2 inches taller and will be playing on a substantially lesser cap hit.

Basically the proposed trade, if we assume Eller-ROR is a wash, is Leblanc, Diaz, 1st rounder, and "roster player" for Erik Johnson. That's an interesting gamble.
